How to speed up timers?

Hello everyone!

Simply my question is how to speed up timers in Adobe
AIR/Actionscript. I recently have encountered a timer on a game and I just want to speed it up. I just am not familiar with flash coding as I have only used C++ and Java but still....
I have seen people doing this through a an executable program that would speed the timer up as the process was running which I thought was ingenious. Now I just want to replicate that with your help!

Anything will help me as at this moment I am doing a lot of research as well.
